tRPOf with Trinket

This article is about a RPOf circuit for the Raspberry Pi using a Trinket, thus a tRPOf.

I'm a software developer, mainly in firmware for many years and still today I really love working on small board in C or assembly. I consider that a "real" programmer job.
Going down on the memory lane (pun intended :) ) it can explains maybe why.
